Document Summary

Week 12: review, loudness: perceptual correlate to intensity, sone and pon, remember there is a degree of subjectivity, pitch: frequency, mels: ratio scale. If you take a pitch and make it twice that pitch, as it gets higher you may not hear that sound: loudness: amplitude, phon and sones, road map, binaural hearing. Binaural summation: binaural loudness summation is a binaural listening advantage, listening to the same stimulus with two ears rather than one. Increase in perceived loudness of the stimulus: 3 db improvement in absolute thresholds for pure tones, under headphones, variable improvement (increase in perceived loudness) with different stimuli (tones vs. speech. Vs. noise) and different transducers (headphones vs. sound field) Binaural fusion: separate signals (to each ear) are perceived as a single, fused auditory experience that originates from one apparent source, whe(cid:374) o(cid:272)(cid:272)urri(cid:374)g i(cid:374) sou(cid:374)d field, the sour(cid:272)e is (cid:862)outside the head(cid:863, when occurring under headphones.
